DOOR.

Application filed April 9, 1925.

To all whom it may concern):

Be it known that I, EDWARD J. SrIEsBAoH, a citizen of the United- States, and a resident of East St. Louis, St. Clair County, Illinois, have invented an Improvement in Doors, of which the following is a specification.

This invention relates to joints and with regard to certain more specific features to means for locking insert panels into door frames.

Among the several objects of the invention may be noted the provision of strong and durable means for mounting insert veneer panels and the like in door frames,

the provision of such said means as will have a neat and graceful appearance and yet not have a high manufacturing cost.

The invention accordingly comprises the features of construction, combinations of elements, and arran ements of parts which are exemplified in t e structure hereinafter described and the scope of the application of which will be indicated in the following claims.

i In the accompanying drawings, in which are shown two of various possible embodiments of this invention,

Fig. 1 isan elevation of a door showing the application of this invention;

Fig. 2 1s a plan view with parts broken away of the various elements of the invention in their positions prior to assembly;

Fig.3 is a perspective view of a preferred form of corner block;

Fig. a is a section taken on line 44. of Fig. 2;

Fig. 5 is a perspective view of a modified form of corner block;

Figs. 6 and 7 are sectional views of possible molding shapes showing characteristic tongues and grooves;

FigFS is an assembled plan view of a modified corner construction illustrating a corner block of alternative angle; and

Fig. 9 is a section taken on the line 9 9 of Fig. 8 showing the arrangement of parts when more than one tongue is used.

Similar reference characters indicate corresponding parts throughout the several views of they drawings.

Referring now more particularly to Fig. 1, there is illustrated at 1 a door comprisin stiles 3and 5 and rails 7 and 9.

he stilesand rails are provided at their Serial No. 21,815.

inner faces with grooves 11 and 13 respectively, see Fig. 2.

Tongues 15 at the ends of the rails 7 and 9 fit into the said vertical grooves 11 0f the stiles for jointing purposes. Thus when the stiles 3 5 and rails 7, 9 are assembled there is provided a framework inwardly grooved. The number of grooves may be one or more. I This framework, however, is not assembled until other parts, to be described, are in the process of assembly.

At the corners of the framework of stiles and rails are provided corner blocks, preferably of the type shown in Fig. 3.

These corner blocks comprise a block of material 16 (usually wood) which may be carved or formed to pleasing shapes on either or both horizontal surfaces.

The preferredform of corner block is provided with grooves 17, 19, 21 and 23 in the four edges thereof. Two of the grooves 17 and 19 meet by means of a beveled portion 29. The grooves are comparable in size to the grooves mentioned in connection with the said stiles and rails. There may be several grooves running parallel, ifdesired.

The edges of the block 16 in which grooves 17 and 19 are cut need not be formed at ninety degrees to one another. The particular angle to be used is left to the discretion of the designer, as illustrated in Fig. 8. In Fig. Sedges 73 and 75- of block 71 are shown to be other than ninety degrees to the frame edge. Theangle between the faces in which grooves 21 and 23 are out, need only conform with the angle between the stiles and rails. named angle is usually ninety degrees.

An ornamental curve 31 may be formed at the inner corner of the corner block 16.

Splines 33 and 35are adapted to fit into the grooves 21 and 23 of the corner block and grooves 11 and 13 of the stile and rail respectively. The splines 33 and 35 are adapted to come flush with one another at the point 37 but not to extend into grooves 17 and 19. The number of splines may be increased if the number of parallel grooves is increased as described.

Placed parallel to the rails and stiles are molding pieces .39 and 11 respectively. These molding pieces may have any one of many cross-sectional shapes. Two illustrative molding sections are shown in Figs. 6 and 7. The ornamental portions of the This last shapes are left to the designers discretion in so far as he makes them match the corner blocks. However, the moldings should be characterized by outside longitudinal tongues 13 and inside longitudinal grooves 45. As a continuation of outside tongues 13, there are provided end tongues 4:? adapted to fit into the grooves 17 and 19 of the corner block 16.

The outside tongues A3 lit into the same grooves into which the splines 33 and 35 fit. The number of parallel tongues may be one or more per piece of molding.

It should be noted that the end tongues 47 do not extend over into the longitudinal projection of the inner grooves A5.

In Figs. 8 and 9 is illustrated the corner block 71 having edges 73 and 75. This block and its corresponding molding pieces have multiple grooves 81 to fit multiple tongues 79 of the stiles 8 and 5 and rails 7 and 9.

The molding pieces 39 and al are shown in Fig. 8 provided with the two outside longitudinal grooves 81, and the original inside longitudinal groove corresponding to the original inside groove 45 of Fig. 2. The groove a5 receives an insert panel 49, to be described.

The Figs. 8 and 9, therefore, show a modification wherein a corner block having an inside angle not equal to ninety degrees is used. These figures also illustrate the use of multiple tongues and grooves with one free spline. The spline'might be fixed or integral. Also, more grooves might be used. End tongues 7'? are provided on the molding pieces corresponding to end tongues 47 of Fig. 2.

Adapted to fit into the inner grooves 45 (Fig. 2) is the insert panel 49. This panel is usually of the veneer type.

The edges of panel 19 are adapted to come flush with the outer edges of the end tongues 17 when all parts are assembled. Likewise the corners 51 of panel 49 are adapted to go in under the rounded ornamental portion 31 of the corner block. The portion 31 may be of any shape whatsoever. The bevel 29 of the corner block grooves allows room for the corner 51 of the insert panel when the portion 31 is rounded as shown.

In order to assemble the parts they are put into the relative positions shown in Fig. 2 and the usual glue applied to the edges of panel 49, grooves and tongues of the molding pieces 39 and 41 and corner blocks 39, and to the grooves and tongues of. the stiles and rails.

Next the stiles and rails are clamped together in the position shown in Fig. 1, clamping therebetween the panel, molding and corner blocks as shown in said Fig. 1.

After the glue has hardened an exceptionally rugged and beautiful door results.

Fig. 5 illustrates a modified form of corner block 58 in which integral instead of separate splines are used.

The modified corner block is made with two grooves 55 and 57 corresponding to the grooves 17 and 19 of the preferred form of block 15. A beveled portion 59 is also employed to join the grooves under a rounded inner corner portion 61.

Instead of employing free splines in the outside grooves, however, there are formed two integral outside tongues 63 and 65 which are adapted to reach into the grooves 11 and 13 of the stiles and rails respectively. These tongues 63 and 65 in the modified form take the place of the loose splines 33 and in the preferred form and consequently are adapted (like the splines) not to extend out into the inner'grooves of the corner block. The number of outside tongues may be one or more.

The described method of assembly is em ployed for the modification.

The word splined, as used in this specification and in the following claims is to be construed as implying means for fastening members by way of integral tongues and grooves or by way of separate splines and grooves.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
